Exploring ComfyUI Basics: Why Separate Checkpoint and KSampler in Workflows?
DavidThi303 · reddit · 2026-07-28
A Reddit user posted a technical question exploring the underlying logic of ComfyUI workflows. The author raises two core questions:
- Why is there a logical distinction between the model weights (Checkpoint) and the sampler (KSampler), rather than feeding text directly into a combined model?
- For Txt2Img, why is an empty Latent Image required as a starting point instead of letting the model decide its preferred initial state?
